removing naturals

[Peter Buhr]

The following is a left-hand octave-exercise for guitar. It has no tempo.  I do
not want the natural symbols to appear in the exercise. I used
"Staff.extraNatural = ##f" is an attempt to eliminate the naturals as per the
instructions on page 6 of the Notation Reference manual, but that did not
help. Is there a way to remove all the natural symbols?

Also, is there a way to increase the font size of the "8" in the "treble_8"
clef?

Setting extraNatural = ##f simply ensures that you don't get (e.g.) a  
natural *and* a flat when a sharpened note is followed by a flattened  
one of the same pitch (e.g., A# followed by Ab).

Since you've used \cadenzaOn, the entire exercise is (according to  
Lilypond) in one measure -- therefore, engraving rules state that the  
naturals have to be there in order to cancel out the previous  
accidentals in the same bar. Notice, for example, that the second  
note on the second line is an F# (octaves), but there are no  
accidentals! No doubt this is not what you want.

If you want to eliminate the naturals, you need to trick Lilypond  
into thinking that these are multiple measures (so that the "C major"  
key signature takes over on each note), or apply one of the other  
accidental rules (as outlined in the docs, e.g. <http://lilypond.org/ 
doc/v2.13/Documentation/user/lilypond/Displaying-pitches#Automatic-
accidentals>).

Override the Clef stencil, and build the markup yourself -- I don't  
know any other way.
See the docs (especially the LSR) for examples of overriding grob  
stencil(s).

Hope this helps!

\override Staff.OctavateEight #'font-size = #2

There is an easier way.  The octavation symbol is
a separate grob, so the following override will
increase its size from the default value of -4,
leaving the rest of the clef unaffected.

Adjust the number to suit.

\override Staff.OctavateEight #'font-size = #1

Trevor

Hi Trevor (et al.),

Cool! Yay, Lilypond!!
[This will definitely be a setting I adjust in my main \include
\init_Lilypond.ily file: I've always found it too small, but have  
been too busy to tweak it.]

Thanks,
Kieren.
